Answer: Exothermic reaction
Explanation:
Exothermic reactions lose energy, or ΔH, when they react.
Answer:
2.4 mole of oxygen will react with 2.4 moles of hydrogen
Explanation:
As we know
1 liter = 1000 grams
2H2 + O2 --> 2H2O
Weight of H2 molecule = 2.016 g/mol
Weight of water = 18.01 gram /l
2 mole of oxygen react with 2 mole of H2
2.4 mole of oxygen will react with 2.4 moles of hydrogen

oxidation reaction
Explanation:
2 Na2O → 4 Na + O2
This is an oxidation-reduction (redox) reaction:
4 NaI + 4 e- → 4 Na0(reduction)
2 O-II - 4 e- → 2 O0(oxidation)
Na2O is an oxidizing agent, Na2O is a reducing agent.
